Worker-Qol 76 – An Instrument For Evaluating Workers' Quality Of Life: A Description Of Its Construction And Key Psychometric Properties
Journal Title: International Journal of engineering Research and Applications - Year 2017, Vol 7, Issue 12
Abstract
Introduction: Quality of Life (QOL) is an individual's perception of his position in life in the context of the culture and value systems in which he lives and in relation to his goals, expectations, standards, and concerns. It involves the presence of physical, mental, and social well-being. Although there are instruments that have been used to evaluate QOL generically, including questions about workers’ QOL, specific instruments for evaluating the QOL of workers have not been found. Objectives: To develop and validate a specific instrument (WORKER-QOL 76) to individually evaluate the QOL of workers in general. Methods: The sample comprised 708 workers of both genders who responded to an initial version of the WORKER-QOL 76 questionnaire that included 106 items, the World Health Organization Quality of Life Scale-Abbreviated Version (WHOQOL-BREF), the Center for Epidemiological Studies-Depression Scale (CES-D), and a questionnaire on demographics and economic classifications. Statistical analyses resulted in a final draft of the WORKER-QOL 76 questionnaire that comprised 76 questions divided into four domains (psychological, social, physical, and environmental), with internal consistency indices of 0.91, 0.88, 0.76, and 0.76, respectively. The test-retest reliability of the scores was estimated, and the intraclass correlation coefficients ranged between 0.78 and 0.93. The correlations between the final version of the WORKER-QOL 76 questionnaire and the WHOQOL-BREF and between the WORKER-QOL 76 questionnaire and the Depression Scale (CES-D) attested to the convergent and discriminant validity. Conclusion: It can be concluded that the WORKER-QOL 76 evaluation instrument has good psychometric properties for evaluating workers' QOL.
